According to Rani Borkar, corporate VP and GM of the Intel Architecture Group, the Haswell processors will offer a huge improvement over the current-gen Ivy Bridge chips when it comes to battery longevity.

In a media briefing, reported by ComputerWorld, Borkar said that in standby or idle mode, the chips will be up to 20 times more efficient. Impressive stuff.

MacBooks first in line?

The improvements are hugely important to Intel's manufacturing partners and consumers who're searching for that holy grail of all-day battery life from a laptop.

Apple's MacBook range may be among the first products to benefit from Intel's new chips.
